Answer:
y - value of the vertex is 49.
Step-by-step explanation:
Given function is f(x) = -(x - 3)(x + 11)
f(x) = -(x² - 3x + 11x - 33)
= -(x² + 8x - 33)
= -(x² + 8x + 16 - 49)
= -[(x + 4)² - 49]
= -(x + 4)² + 49
Comparing this equation with the vertex form of a quadratic function,
f(x) = -(x - h)² + k
Where (h, k) is the vertex of the function.
Vertex of the parabola is (-4, 49)
Therefore, y-value of the vertex is 49.
3x12/(4+2)
36 divided by 6 = 6
Your answer is A 6
Answer:
52 : 14
Step-by-step explanation:
multiply the numbers by 2
Answer:
Step-by-step explanation:
Use tangent:
We have:
Substitute:
<em>multiply both sides by 14</em>
5x^2 - 6x^2 = - x^2 so its either c or d.
and + 9x - )-3x) = 9x + 3x = + 12x
so the answer s C.
